Windows only: Free application Explore&Burn adds an entry to your right-click context menu that allows you to quickly burn files and folders to CD or DVD.

This right-click utility is dead simple: Click any file, folder, or disk image (e.g., ISO, IMG), select the Burn to disc context menu option, and go through the very quick burning wizard. The application supports most types of burnable media (including Dual Layer discs) and skips the bloat that accompanies a lot of burning software, opting instead for a completely pared down interface and footprint.
